To all whom, it may concern:

lie itknown that I. FREDERICK R. (iOOL- Mama citizen of the UnitedStates. residing at- Binghamton, in the county of Bron-me and State ofNew York, have invented cerl tain new and useful Improvements inAutowhich the following is a specification.

piano players of that general type which are controlled by the passageof a perforated 'music sheet over a duct bridge. the primary 1 object ofthe invention being the provision of novel means for automaticallybringing a new spool into position and removing the E old spool as soonas't-he-latter has finished playing.

" A further object of the invention is the provision of a magazineadapted to contain a number of spools, means being associated I with themagazine for bringing the various j spools successively into positionfor playmg, and removing them from position when 5 '-For a fullunderstanding of the invention, reference is, to be had to the followingthey have finished playing.

A still further object of the invention is i the provision of a magazinefor automatic piano players which may be constructed to hold either alarge or small number of spools, which operates in a positive andreliable manner to move the spools through the magazine and bring'theinsuccessively into action, and which automatically rewinds each spoolwhile the following spoolis being played.

With these and other objects in viewythe invention consists in certainnovel combinations and arrangements of the parts as willinorefullyappear as the description procoeds, the novel features thereofbeing pointed out in' the appended claims.

' desdription' and accompanying drawings, in

Fig. 8 is a longitudinal'vcrtical sectionalview on the 'line I Fig; 2. Fig. iis an enlarged plan detail view of theresetting cams and the main lever of the resetting mechanism. Fig. 6 is"a detail view of one end of the shield which is employed for preventingthe kicker from injuring the music sheet. Fig. 7 is a i sectional viewthrough the outer end iof one inatic Mechanism for Piano-Players, of jof the music sheets showing the spring p 1 which is applied thereto.Fig. 8 is a detail Thepresent invention relates to automatic sectionalview of the resetting mechanism,

2 the parts being shown in full lines in the ted lines in the positionassumed when a new spool has just dropped into posit-ion. Fig. 9 is anenlarged sectional viewthrough the duct bridge, and Fig. 10 is anenlarged view showing the springs for preventing backward movement ofthe spools through the magazine.

Corresponding and like parts are re ferred to in the followingdescription and indicated in all the views of the drawings by the samereference characters;

Referring to the drawingathe numerals 1 designate a pair of castings orplates which have a spaced and parallel relation to each other andconstitute the sides of the main frame upon which the mechanism ismountedythe said plates being rigidly connected by cross bars 2. Theseside plates 1 of the main frame are provided u on their inner faces withcorresponding on less runways 3 adapted to receive the ends of thespools 4. Each of the runways is shown as comprising a lower horizontalportionB and an upper horizontal portion 3, the said horizontal portionsof the runway being connected at the rear end of the magazine by acurved portion 3, and at the forward end of the magazine by a curvedportion '3 The portions 3, 3", and 3 of the runway are ffilled with thespools 4 which are moved f step by step rearwardly within theportion 3of the guideway, around the portion 3. and forwardly upon the portion 3,the various spools being brought successively into action as they dropfrom the forward end of the portion 3 of the'runwayrto the forward endof the portion 3 thereof. It may here be noted that -'the spools in theupper .pdrhion 3 of the runway merely rest loosely thereon so that theycan readily be removed and replaced by other spools when desired.

Referring to Fig. 3 of the drawing the spoolf l which is in position forplaying rests upon supporting rolls 5, and 6, the former being fixed inposition and being continuously rota-ted while the player is equivalentelement herein termed a duct bridge 10, and finally drops upon an apron11 where it rolls up loosely on itself. The

feed rolls 12 and 13 for drawing the music sheet from the spool arelocated under the duct bridge 10, the feed roll 12 being rigid with a.shaft 14 which is positively driven when the player is in operation,while the feed roll 13 "1s journaled upon the arms 7 and merely servesto press the music sheet 9 against the'roll 12. The duct bridge 10 is ofthe usual construction and is deslgned to be connected to some suitablelayer mechanism such as that disclosed in atent No. 917,288 which wasgranted to me on April 6, 1909. This duct bridge is shown as suspendedby means of a' pair of hooked hangers 15 which removably engage one ofthe cross bars 2. v

Referring further to Fig. 3, it will be observed that the spool 4:?which was previously played is resting upon an idler 16 and a rewindingroller 17, the top. of the said spool bei'ng'engaged by a positioningroller 18 which may be suitably weighted or otherwise caused to bearupon the spool 1 so as to hold thesame in 'contact with the rewindingroller 17. The positioning roller 18 is journaled between a pair ofrearwardly extending arms 19 which are pivotally connected to the frameat 20 to admit of the positioning roller being moved up and down,

' the downward movement of the said roller a second rock shaft 25.

being limited by lips 21 which project laterally from the arms 19 andare adapted to engage ribs upon the main frame.

The rock shaft S which carries the arms 7 is'aIso provided with a crankarm 22 which is connected by a rearwardly extending link 23 to anupwardly extending arm 24 upon A coil spring 26 engages this arm 2-l andnormally tends to draw the same rearwardly so as to rotate the rockshaft 8 and swing the arms 7 into the position indicated by full lineson'Fig. 8. Rigid with the second rock shaft 25 and preferably integralwith the arm 24 is the resetting lever 27, the said lever being shown asextending forwardly from the rock shaft and having the end thereofextended upwardly to provide a support upon which the kicker 28 ispivotally mom ted. The forward end of the kicker 28 normally projectsdownwardly into the path of the spools, while the upper end thereof isprovided with a roller 29 adapted toi heengaged by a cam 30.u 'ion aresetting shaft 31. This resetting shaft 31 is journaled upon the sides1 of the main frame and is also provided with a second cam 32 adapted toengage a roller 33 upon the main lever 27. The resetting shaft 31 isnormally locked against rotation with the cams in the position indicatedin Fig. 5, the cam 30 being out of en agement with the roller 29 of thekicker an the forward end of the kicker being held away from the spool4" by means of a spring 34 connecting-the kicker to the resetting lever,while the roller 33-of the lever 27 is eng ed by the steep portion 32 ofthe cam 32. said lever 27 is thereby held in a depressed positionagainst the action of the spring 26, and the arm 2% swung forward so astomove the arms 7 of the rock shaft 8 into the position indicated uponFig. 3. For the purpose of bringing a new'spool into position, theresetting shaft is given one complete revolution. The initial movementof the resetting shaft moves the steep portion 32 of the cam 32 awayfrom the roller 33 so that the said roller can enter the depressed orshallow portion 32 of the cam and permit the lever 27 to swing'upwardly,thereby moving the kicker 28 out of the path of the spools and alsooperating through the arm 24 and link 23 to rock the shaft 8 and swingthe arms 7 into the position indicated by full lines' on Fig. 8. Thesupporting roll 6 is thereby moved away from the supporting roll 5 so asto drop the spool 1. and the feed roll 13 is moved away from the feedroll 12 so as not to obstruct the downward passage of the spool 4 Acontinued rotation of the shaft 31 rings the roller 33 of the resettinglever 27 into engagement with a substantially circular portion 32 of thecam 32 so as to partially depress the lever 27 and thereby swing thearms 7 forward a willcient amount so that the supporting rolls 5 and 6will engage the next spool as soon as it is forced over upon the same.The cam 30 then engages the roller 29 of the kicker 23 and moves therear end of the kicker upwardly. thereby causing the forward end of thekicker to engage the spool 4 and move it forcibly into the positionpreviously occupied by the spool 4". all of the spools in the magazinebeing thereby moved forward one step. and that spool at the forward endof the upper portion of the runway being forced over upon the supportingrolls 5 and G. The sl-ipporting' roller 5 rotates the spool in such adirection as would wind the music sheet. thereon, and while the spool isthus rotating the hooked projection at the end of the music sheet isengaged by a resetting book 36 which was moved upwardly between the feedrolls. This resetting hook projects upwardly from a. rod 37 connecting apair of levers 38 which extend rearwardly along opposite sides of themain frame an l ale pivotally coniaected thereto at interpoints betweentheir ends, as indi cat'edtat; The rear ends of these levers .38 areconnected by links 40 to crank arms r 41 at opposite ends of. theresetting shaft 31,

.the said crank arms being so positioned with relation to the beforementioned cams as to move the resetting hook 36 upwardly when the feedrolls are separated and the new spool'is forced into position. In orderto move the nose of the resetting hook 36 forwardly and insure a properengagement thereof with the hooked projection upon the music sheet, aspring 4-2 may be utilized, the

said spring-being secured to a cross bar 43 and bearing loosely againstthe back of the "hook member ash is raised. A continued ,movement of theresetting shaft 31 operates thereby produces a further rotation oftherock shaft 8 so asto cause the feed roll 13 to'hold the music sheettightly against the \feed roller 12. At, thispoint, attention may bedirected to the fact that the end spool {1 upon theupper portion 3 ofthe runway is prevented from dropping accidentally upon the sppol l bymeans ofa shoulder 3 at the bottom" of the runway. When the spool is Iforcedforward ly it passes readily overthis shoulder, although it isheld thereby against prematurely dropping into position. It will furtherbe observed that the resetting shaft 3l is;provided with a timing disk44: and a gearwheel 45,,the said timing disk being formed with .a notchor opening 46 into whichone end of a slidably mounted counter,-shaft;47normally projects. This coun- V ter-shaftfis journaled upon one of theside piecsil ofthe mainframe and a bracket 48 projecting therefrom, anda pinion 49; upon the counter-shaf t is thrown into mesh with the gearwheel whenthe counter-shaft is moved to withdraw the end thereof fromthe opening of the timing disk, the said pinion qbeing out ofengagementbtvith the gear wheel while the end of the counter-shaft iswithin "the "opening of the timing. disk. A shipper lever 50 which Qhasa be ll crank for mation is pivotally mounted upon the.

bracket 48 and engages the counter-shafts? arena the same within itsbearings; a spring 5i being appliedto the shipper lever for'normallyholding the counter-shaft in engagement with the'open'ing of the timingU disk. gin clectl'ic switch,52 is also mount- I ed upon the bracket 48,and the switch lever gagestlie counter 'shaft 47 so that the said.

53 is formed with an'cxtension 53* which en- 7 switch is closed whenthe; shipper lever 50 1s moved to retract the countenshafttromtheopening of the timing disk. The eni GBJ'g'agenient' of tit ecounter-shaft 'with"'the opening of the timing disk normally locks theresetting shaft 31 against rotation and holds the various members in theposition indicated in Fig. 3, while when the counter shaft is withdrawnfrom the opening 46 of the timing disk and the pinion 4-9 thereonbrought into mesh with the gear wheel free end of each of the musicsheets 9 has a, spring strip 54 applied thereto, the said spring stripnormally tending to assume a coiled .aposition so as to prevent themusic sheets from unwinding from the spools while the spools are passingthrough the magazine,

and also forming a nucleus or center about which the unwound music sheetrolls as it. is drawn from the spool and dropped upon the apron 11.- Thebefore mentioned hooked projection 35 .is preferably formed by returningthe outer end of the spring strip 54:.

An electric motor 55 is util zed for open ating the piano player, andpower is transmitted through the medium of the pulleys and belts 56 to amain drive shaft 57 which is provided with a gear wheel 58; A chain orbelt 59 passes around this gear wheel and also engages a gear wheel 60which is rigid with the supporting roller 5, a gear wheel 4 61 which isrigid with the countei shafti's', a gear wheel 62 which is rigid withthe re winding roller 17;, and a gearwheel 63 which is rigid with thefeed roll 12. Electric current is supplied to the motor 55- through thewires 64:, and a switchtiti 'is employed for opening and closingthe'circu'it. I This switch is normally held in an openposition by meansof a catch 66, and is fjconnected to a pneumatic 67 by means of'a rod68'. It will also beobserv ed that wires 69- lead from opposite sides ofthe main switch to the auiiiliary switch 52, and that the pneumatic 67is connectedfby a pipe 70 to a'second pneumatic '71, the said secondpneumatic bemg connected by a rod 72to one end of a lever 73 which ispivoted upon one side of the magazine, the upper end of the lever beingconnected by a link'7-la to the shipper lever 50. 7

The various parts of the mechanism are osition bymeans of the catch 66,the spool P being in position for playing while the spool 4 is iii-positionfor being rewound. When the switch 65 is released, either1nanually or by dropping a coin upon a pan 75v carried by the catch 66,the said switch is normally in the position indicated in Fig. 3 with themain switch 65 held in anopen closed-bysmeans of the s ring 76. Themotor is then started and t e various el ments driven. by the chain 59set in motio The" feed rolls draw the music sheet fr the.

spool 4. over the duct bridge 10 so as t turns in such a direction as toresist unrolling of the music sheet from the spool 4*,

thereby acting to produce tension in the music sheet and hold it firmlyagainst the duct-brid e. The counter-shaft 47 is also revolved, utmerely acts as an idler, since the pinion 49 thereon is out ofengagement (3. may be'carried by the arms 7.

with the gear wheel 45. As soon as the end of the music sheet isreached, an opening therein uncovers a certain duct 77 in the ductbridge and admits airinto a pipe 78 leading to the pneumatic 67. Air isthen exhausted from the pneumatics 67 and 71 so as to collapse the same,and this action of the said neumatic 67 draws the switch blade 65 ackinto engagement with the catch 66 so as to open the switch, while thecollapsing of the pneumatic 71 swings the lever 73 so as to actuate theshipper lever 50 and pull the counter-shaft 47 out of the opening 46 ofthe timing disk 44. The pinion 49 upon the said counter-shaft issimultaneously brought into mesh with the.

gear wheel 45 and the auxiliary switch 52 closed. The motor 55 continuesto run as long as this auxiliary switch is closed and the various artsof the machine are still driven as be ore. The motion of the counter-shatt 47. however, is now imparted to the resetting shaft 31until'the said shaft has com leted one revolution, when thecounter-siaft 47 again enters the opening 46 of the timing disk 44 so asto lock the; same against motion. This sliding move-' ment of thecounter-shaft also serves to open the auxiliar switch 5% so as tocompletely shut off t e supply of electric current to the-motor 55. Thesingle revolution of the resetting shaft 31, however, acts as has beenpreviously described to bring a new spool in position for playing anddrop the old spool down upon the rewinding roller. In order to preventthe kicker .28 from injuringthe music sheet, a guard plate 79, which isillustrated more clearly in Fig.

The machine is now ready to play the new spool as soonas the main switch65 is again closed, and this operation will be repeated indefinitely,the various spools being forcwbstep by step around the runway andbrought. successively into action. in order to prevent backward movementof the spools through the magazine, spring delenls 80 may be applied tothe sides 1 of the frame sons to bear frictionally' against the ends ofthe spools and engage depressions 81 therein. These spring detent-s areshown more clearly in Fig. 10, and it will be observed that the spoolsare perfectl free to move forward when the kicker 28 is set in action,although they are held securely against any backward movement} I Havingthus described the inventiomyvhat I claim as new and desire to securebyikg ters Patent, is
